10 Claims.

My invention relates to collapsible reels and relates particularly to reels for holding rayon cakes of thread.

Heretofore, rayon cakes have been placed upon a cakeholder which consisted of a circular base to which a cylindrical support was attached; an insert spread out the center of the cake and then the insert together with the cake was placed over the support. The difiiculties encountered in winding rayon cakes-upon the holders of the prior art originated because the rayon cakes are without any body orself support. Furthermore, in mounting the cake on the prior art holders, the insert must be held contracted by using one hand (this is tiring especially when the strong spring inserts are used) and the other hand is free to push the cake over the insert.

In order to simplify the mounting of rayon cakes upon suitable holding means, my invention consists of a protruding contractihle reel which is adapted to be mounted so that a foot-controlled mechanical actuator will contract the reel.

The operation of contracting the reel lay means of a foot pedal leaves the hands of the attendant free, so that the mounting of the rayon cake upon the reel. is easily made, and-can he carried out carefully by using both hands, as contrasted to the prior art devices thereby increasing the quan tity of work and thereby increasing production.

Other objects of my invention are to provide an improved device of" the character described, that is easily and economically produced; which is sturdy in construction, and which is highly efficient in operation.

With the above and related objects in view, my invention consists in the detailsof construction and combination of parts, as will be more fully understood from the following-description, when read in conjunction with the accompanying drawing in which:

Fig. 1 shows in fragment the first embodiment of my invention with the reel extended.

Fi 2 is a similar representation but with the reel contracted.

Fig. 3 shows a fragmentary view of amodification of my invention.

Fig. 4 is a view of the modification with the reel contracted.

Fig. 5 is a fragmentary sectional view of the reel itself.

Fig. 6 is a detail of the telescopic arrangement between the reel and the mandrel.

Fig. 7 is a holding handle.

Fig. 8 is a view of the movablecarrier whereby .1.

2 cakes or rayon may travel a continuous flow to and from the mounting tables.-

Fig= 9- is a side view of the movable carrier shown in- Fig.- 8.

Referring now in detail totlie drawings,- I show a rayon-cake expanding and col-lapsible ree'l and a root control wherein the reel has a hollow shaft l whichis encircled by a fii're'd collar 2- as well as two sliding rings 3 and l; the sliding rings 3 4 are tied firmly together with a plurality of light bars 5'. The-cake supporting rods 6 are pivotally connected by links 1 to the slidingrings 3, eachor the links 8- is pivoted at one end to the fixed collar 2 and is pivoted at its other end to the supporting rod 6; and each of the links 9 pivoted at oneend to the: sliding ring 4 and its other endto thesupporting ring 6. The sliding rings 3' and 4, together with the pivoted ends or the links 1-; i3, and ll Cause the rayon sup-porting rods 6 to move substantially parallel t but closer to or away. from the hollow reel shaft L- The links 1, 9, the rod 6, and the connecting bar 5 forms a parallelogram.

A spiral spring 3'6 surrounding the reel shaft pushes the Supp ing bars 5 into an extended or normal position, as illustrated in Fig. 5.

Within the hollow. reel shaft I is a rod IDA whichrhasa single cross pin it extending through both of the guide slots H. The cross pins l0 by abutting the extreme (upper and lower) ends of the guide S1017 limit the pO'Sitit-i (if the supl 'i' g rods 6. other words the spring 38 presses down-war'dly'on the movable ring 3 carrying-withit r 4- and the ring 4 presses downwarslyon pins It sothat the lower end of the slot it is contacted by the pins it thereby eX- tendin the reelto its normal position.

The reel shaft I has rigidly secured upon its lower end a shoulder ring or flange l which w flange extendsoutwardly from the end of the shaft. The r el has the lower of the shaft l loosely placed: upon a hollow cylindrical ring [2 through which a push rod or shaft I"! passes, and

the ring Ii is fastened to the surface of the table H; A holder, f3 is clamped tothe ring l2 and theholder f3 pivotal-1y support two claw-levers orhoohs' is. The. hook end of the claw levers F5 clamps upon the shoulder; ring r of the reel sh-aft l" and the other, ends of the claw levers are pushed apart By a cam I9 and its Wide end It. Upon releasin the claw levers they are sunset togetherby a tensionspring is which constrain the claw levers F5 to assume the inoperat ve sides- Fig. 1.

Referring now in greaterdetail to 5, I

show the shaft I having a spring 38 anchored at its upper end to a stop 2A which is securely fastened to the shaft I and the lower end of the spring pushes upon the slidable ring 3 so that the rin 3 tends to be pushed downwardly at all times in order to spread the supporting rods 6 since the connecting links 3 and 9 move outwardly.

A freely movable rod 10A within the shaft i has a pin In pass therethrough and also through the elongated slots H, II in the rod. The pin I is adapted to abut against the under side of the upper movable ring 4 so that when the push rod ll abuts against the end of the rod lllA it moves the pin [9 as well as the ring 4 upwardly in order to collapse the reel. If the rod 11 were released the spring 38 would tend to push the reel to its open position as hereinbefore explained. However, to prevent the opening of the reel, I

provide a lock 34 which has an opening 36 therein through which the shaft l passes. An extension 56 on the lock 34 oscillates in a complementary groove on the slide 4. An extension or handle 35 also is integrally formed on the lock 34 and a spring 42 anchored to the slide 4 abuts the lock 34 thereby urging the lock to bind against the shaft l, thereby holding the slide 4 in position. To release the lock to enable the spring 38 to spread the reel, I press downwardly upon the handle 35 of the lock 34 thereby permitting the lock to be inoperative so far as holding the reel in closed position.

To repeat, the rod IT projects inside the hollow shaft l and abuts the rod A which is attached to support carrying pins Ill. H also projects through the cylinder I2 and continues to the tapered or conical surface IS on the leading guide member 18 of the extended end of the rod I! which rod also is pivotally joined to a lever or pedal 20 which is pivoted at 21 to a support 22 that is placed on a floorboard 23.

By moving the pedal 20 in the direction of the arrow shown in Fig. 2, the rod I1 is moved upwardly through the cylindrical guide I2'thereby raising the tapered surface or cam IS} on the guide member l8 to shift the lower ends of the claw levers l5 apart so that the upper surface of the shoulder ring I of the reel shaft l is grasped. The reel is then firmly held to the cylinder 12, as shown in Fig. 2. The upward movement of the rod H through the hollow shaft I causes the rod H to engage the rod IOA on which the pin I0 is carried so that the cross pin l0 raises the upper slide ring 4 against the reaction of spring 38 and hence the lower slide rin moves in unison with the upper slide ring 4 thereby folding the supports 6 close to the center hollow shaft I.

By stepping on the foot pedal 20 the reel is folded together, i. e., from its extended position in Fig. 1 to the folded position corresponding to Fig. 2, then a cake of rayon may be grasped with both hands and placed conveniently upon the reel, as is clear without further explanation. Afterwards, when the reel has been fitted with a rayon cake, the pedal 20 automatically swings back to its idle position; the rod I! also is moved to its lowered position so that the reel is restored to its outstretched position by the spring 38, and the claws l'5 open so that the reel may be removed.

Then the normally extended reel, upon whose supporting bars 6 the rayon-cakes rest under tension, may be removed from the cylinder 12 and the rod l1 and the reel may be brought to an- The rod other working location, e. g., for the purpose of unwinding the rayon cakes.

If desired, the ring 12 can be fastened to support [3.

It is evident there can be a plurality of these holding devices hereinbefore described, arranged in a row on the same work table.

The holding means of my invention may also be employed with reels which are not shifted from their working positions, the reel may then be fixed to the machine.

The holding means corresponding to Figs. 3 and 4 is distinguished from the described embodiment such that the reel is seated in an opening by means of its hollow shaft I, which open ing is provided in a supporting mechanism [4A, which may be a part of a machine such as a winding machine. Two nuts 24 and 25 screwed upon the threads on the reel shaft I secure the reel firmly to the support M. The rod [1 is here inserted directly into the hollow shaft l of the reel. The operation of the reel is similar to that embodiment of the invention already described. The rayon mass taken up on the reel is then available without further handling right at the adjacent work location of the machine.

It is equally suitable in all applications if the reel, while being fitted out with the rayon mass assumes a vertical, inclined, or if need be, horizontal position. Obviously, the changing of the reel diameters with corresponding development depends on the working mechanism exterior of the reel shaft, instead of the rod projecting inside the hollow shaft. The divided mechanical actuating assembly may be changed by the attendant by using their hand or their knee instead of foot-control, further. The assembly for holding the reel may, under condition, be molded integrally with the support, and it may be at the end of the machine or upon a table.

In many factories, it is recommended that this work be divided and that one or more girls be developed as cake mounting specialists. These girls are given separate tables apart from the winder where the mounting of the cakes is done expertly and rapidly. A portable supply frame, generally designated as F, is adapted to pins Fl on which the reels may be mounted. The frames may be pushed to separate mounting tables where the specialists mount the reels and then the mounted reels can be placed on the portable supply frame or carrier so that there is a continuous flow of mounted cakes from the mounting tables. The operator, therefore, loses no time in laying on the cakes; she is able to attend to many more reels. If cakes of thread are bad running, they may be returned on the same reel without further handling by way of the portable frames, checked, and if necessary, unreeled on a slow running machine by rotating the reel. Hence, the operator loses no time With bad cakes.

Other objects of my invention are to provide a carrier for cake wound reels to go from and to the winding machine or special winding places or to a table, and it may be at the end of the machine or upon a table.
